TREGWINIAN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cornwall local authority area over time, sourced from the HPI. The two TREGWINIAN sales from November 1995 and September 2021 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the November 1995 sale was for 22% above the HPI. So the extrapolation line tracks at 22% above the HPI over time, until the September 2021 sale, where it rises to 249% above the HPI. The line then continues to track at 249% above the HPI.

What might TREGWINIAN be worth now?

TREGWINIAN might now be worth an estimated £1,526,664.

This is based on house price inflation of 13.1%, between September 2021 and February 2025, for detached houses, in the Cornwall local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 13.1% inflationary increase is applied to the most recent sale price for TREGWINIAN of £1,350,000 on 28th September 2021. For the value to have increased from £1,350,000 to £1,526,664 over the four years and seven months to February 2025, the following assumptions must hold true:

• The value of TREGWINIAN has moved in line with the HPI for detached houses in the Cornwall local authority area.
• The September 2021 sale price of £1,350,000 represented a fair market value for the property.
• The size, condition, and specification of TREGWINIAN has not materially changed since September 2021.
